TRAIN-STQPPINGJDEVICE.

Specification of Letters Patent.

Application filed Octoberv 31, 1913, Serial No. 798,564. Renewed March 30, 1916. Serial No. 87,847.

I which will cause a train to stop in case the engineer runs past a set signal.

Another object of the invention is to so construct the train-engaging device which is mounted upon a semaphore pole that it will be movedto a set position when the semaphore arm is set to stop a train.

Another object of the invention isto provide an improved train device which will operate the throttle controlling the air pipe and after passing the signal will leave the throttle in the adjusted position so that it may be returned to its original position by the engineer.

This invention is illustrated in the accompanying drawings wherein Figure 1 is a view showing the signal set to stop a train and the train device about to engage the contact arm carried by the pole; 'Fig. 2 is a top-plan view with the roof of the cab broken away and the pole shown in'section along the line 22 of Fig- 1; Fig. 3 is a view similar to Fig. 1, but shows a modified construction.

The air pipe 10 enters the cab 11 and is I provided with a control throttle 12 so that the engineer can apply the air brakes when necessary. A lever 13 is pivotally mounted upon the top of the cab and is connected with the throttle 12 by means of the flexible connection 14: which may be a chain as shown in Fig. 1, or a cable as shown in Fig. 3. It should also be noted that the lever 13 may extend vertically as shown in Fig. 1, or horizontally as shown in Fig. 3. The device for operating the lever 13 is pivotally mounted upon the semaphore pole 15 beneath the semaphore arm 16 and is connected with the "semaphore arm by means of a I rod 17 so that the operating device will move tending bars 19 and cross bars 20 and 21. The longitudinally extending bars 19 are carried beyond the cross bars 21 to form arms 22 which are pivotally connected with the pole 15 by means of the bolt 23. This operating device is formed arcuate so that when the lever 13 hits the operating device, the lever will not receive a violent blow which would be liable to break the lever or the flexible connection, but strikes the operating device with a glancing blow which causes the lever to swing upon its pivots and draw the flexible connection to move the throttle 12 and permit the air to operate the air brakes.

The operating device 24 which is used in the form shown in Fig. 3 is pivotally connected with the pole by means of the bolt 25 When the station master wishes the train to stop at his station, he sets the semaphore arm and this causes the operating device to extend horizontally as shown in Figs. 1 and 3. When the train approaches the station, the engineer is supposed to see the set signal and stop the train, but it very often happens thaton a foggy night the engineer cannot see the signal and runs past the station. This will be impossible when the train is applied with thissafety device since the lever 13 will strike the operating device carried by the semaphore pole and this will cause the throttle to be opened so that the air brakes can be operated. The train will then be brought to a stop and the engineer must then manually operate the throttle 12 before the train can be again started. It will thus be seen that a device has been provided which Will make it impossible for a train to pass a set signal without stopping,

and it will also be seen that a device of this character has been provided which is very simple in construction and which will operate very efliciently since there is no danger of the lever or flexible connection being broken when striking the operating device.

What is claimed is:

In a train stop of the character described a station device comprising a support, an operating device carried by said support,

said operating device comprising an arcuate 7 body portion, longitudinally extending bracing bars forsaid body portion, cross'barsextending from said longitudinally extending 7 bars to said body portion, said longitudi support andengaging said arms to pivotally mount said operating device a signal car-- ried by said support, and means connecting said signal ith 'said operatingfdevioefor v causing said operating deviee to be 'ino'ved; '7 to a set position with said signal; I o In testimony whereof I aflix my signature 1;.
